Serial No. 410,395.

My invention relates to an improvement in chair seats and couch bottoms, and my'object in general is to provide simple and effective attachment means for supporting 5 a resilient bottom or one or more members thereof at different elevations within a chair or couch frame and/or in various relations n respect thereto. The attachment means includes a simple clamp and connecting de- 10 vice adapted to be readily fastened to a chair or couch frame, whereby the resilient bottom and other parts as well may be secured in place and the assembling operations simp ified and expedited and labor and lfi' cost reduced.

Referring to the accompanying drawings, Fig. 1 is a sectional view of a corner of the couch frame embodying my improvement, and Fig. 2 a similar view showing a subsimilar spring bottom supported at a higher elevation within the frame. Fig. 3 is a sectional view corresponding to Figs. 1 and 2, showing a modified construction of spring bottom, suspended within and 2 connected to the frame by my improved at tachment means. Fig. 4'is a perspective view of one corner of a chair or couch frame,

including a pair of my improved attachment members for supporting a flexible resilient solseat or bottom within the frame. Fig. 5

is a perspective view showing a corner portion of a flexible base member for a resilient seat or bottom, including a pair of my improved attachment members. 35 In manufacturing u holstered furniture, especially chairs and avenport couches, it is customary to tack webbing within the frame and to build up. a spring structure thereon to provide a resilient seat which ineludes padding or upholstering the upholstering being tacked to the woo en frame, and the springs being tied by cord and placed under tension.

The present improvement is a departure 4 from such old ractices in that I provide a yielding flex1 le suspensory support A made of woven material such as canvas, which is suspended within an open rectangular frame B having side and end rails bmade of wood. The suspensory support A made of woven material is connected at spaced intervals with the side and end rails of frame B, and the present invention deals more especially with the attachment devices used in that connection.

These attachment devices consist of metal hangers or clamps C made of flat stock or strap material, which hangers or clamps include a main body portion 2 having a longitudinal slot 3 near one end thereof, and a perforated ear 4 struck up at right angles inwardly from body 2 relatively near its opposite end. Each end of the hanger or clamp is bent outwardly at right angles to provide lateral attachment flanges 5 adapted 'to overlap and seat against the upper and lower flat edges of the wooden rails bof frame B. The flanges 5 are perforated or provided with nail openings 6 to permit them to be firmly fastened to the rail.

Moreover, each flange or bent end 5 is provided with a channeled rib 7 4 transversely thereof adapted to extend longitudinally of the rail, whereby a corrugated or sinuous wire D may be secured to the edge of the rail, preferably to the upper edge. Thus, the clamp A serves as an attachment member for the flexible bottom A and also as a fastening means for wire D. The customary practice is to place the springs under tension by tying hemp cord to the springs and then tacking the cord to rails b. Wire D permits the cord to be drawn to apply any desired tension at an place lengthwise of the rail, and then easily tied, thereby eliminating the use of tacks which cut and tear hemp cord and loosen or slip very readily, under tension. The woven member A is preferably provided with a border wire 8 to re-enforce or strengthen it, and member A is suspended from the'hangers or clamps B by dual means comprising short helical wire springs 9 and small metal loops or keepers -10. The helical springs 9 have hooked ends adapted to be connected to border wire 8 of member A, and to the perforated ears 4 on the hangers or clamps O. The loops or keepers 10 are connected to border wire 8 and project through the slots 3 in the hangers or clamps C where they are anchored hanger or clamp is fastened upon the rail,

the enlarged ends 11 are pressed flat against the body of the hanger or clamp and clamped tightly against the inner flat face of rail b In practice, some of the hangers or clamps C are fixed to the frame rails with the ears 4 adjacent the lower edge of the rail, and similar hangers or clamps are secured to the rail in inverted positions relatively to the first set of clamps, thereby bringing or placing the ears 4 on the second set of clamps near the upper edge of the rails, thereby placing slots 3 on the same clamps in substantially the same horizontal plane as the ears 4 on the first set of clamps. In that way, the woven base member A may be connected with all the clamps within the frame by helical springs 9 and also by keepers or loops 10. Briefly, a dual connection may thus be made with the same kind of hangers or clamps, providing the hangers or clamps are secured in part in inverted position on the frame. Moreover, the duplicate construction of the flanges at, opposite ends of the brackets or clamps thereby permit the same brackets to secure a sinuous or corrugated wire D in place at either or both edges of the rails-bregardless of whether the hangers or clamps are reversibly seated on the frame. A further advantageous result flowing from a reversible-hanger or clamp such as described is that the suspensory bottom A maybe suspended at different elevations within the couch or seat frame B, see Figs. 1 and 2. Either the level of the upholstered seat may be changed, or spiral cushioning springs E of diiferent length or size may be utilized in building up the resilient structure; Also, other forms of spring structures may be supported and suspended by the same brackets or clamps within the frame A, say for example, as exemplified in Fig. 3, wherein base member A is supplemented by a second piece of woven fabric F stretched at'a higher elevation within frame B by helical springs 9'. In this resilient bottom a set of s iral springs G are confined under tension between the two suspensory members A and F.

What I claim, is: v

1. Suspensory means for resilient chair seats and couch bottoms, including a reversible clamping hanger having right-angled end portions adapted to embrace a rail, the main body of said hanger being slotted near one end and having a perforated ear projecting therefrom near its opposite end.

2. Suspensory means for resilient chair seats and couch bottoms, comprising a clamping hanger having a perforated ear and a detachable keeper at one side thereof,

and formed with perforated extremities bent at right angles to permit said hanger to be secured to a rail.

3. Suspensory means for resilient -chair seats and couch bottoms, comprising a clamping hanger having a slot and a pen I forated car at one side, and an larly bent end portions adapted to fit a rail, including a1 keeper adapted to project through said s 0t.

4. Suspensory means for resilient chair seats and couches, comprising a clamping hanger having means at one side thereof adapted to connect a resilient bottom thereto, and including an angular attachment portion adapted to embrace a rail and formed with a seat adapted to confine a longitudinally-extending element laid upon said rail.

5. Suspensor means for resilient chair seats and couc es, comprising a clamping bracket having angularly-bent end portions,

adapted to embrace a rail, each end portion having a transverse groove therein, and the main body of said clamping bracket having means for suspending a base member for a resilient bottom therefrom.

6. Suspensory means for resilient chair seats and couches, comprising a hanger having right-angled end portions, one of said angular portions being grooved transversely to confine a wire, and the main body of said hanger having spaced means thereon adapted to provide separate suspensory connections for one or more members of a resilient bottom.

7. Suspensory means for resilient chair seats and couches, comprising a hanger having right-angled end ortions grooved transversely, and a main body portion provided with a perforated ear and a slot relativel' near the opposite right-angled ends thereof:

In testimony whereof I aflix my signature.
